HEATING- .AND VENTILATING APPARATUE.

Application filed February 17, 19:37. Serial No. 168,867.

This invention relates to improvements in heating apparatus and systems and more especially to a heating system which is particularly adapted for use inheating large buildings such as factories, ofiices, schools, churches, etc., and has particular reference to an improved means for positively and mechanically circulating and distributing hot air in connection with heating units or systeins thereby producing what is known as forced drafts.

The main object of the invention is to pro vide a generally improved heating system of the type mentioned which will be simple in construction, cheap of manufacture and efficient in use.

A further object of the invention is the provision of an improved arrangement of hot air accumulating and distributing chambers and pipes which is adapted to be readily connected to heating units or systems already installed, as well as to form a component part of new hot air heating systems.

Another object of the invention is to provide a system of the character described which may be operated as a ventilating and cooling system during the summer months.

Another object of the invention is to provide for a novel and improved form and arrangement of mechanical air circulating device of the motor driven blower type in which the motor is arranged outside of the conduits so as not to be atl'ected by the heat and in which a single blower may be used to force the draft in the plurality of conduits A still further object of the invention is to provide a motor driven air circulating device which in no way interferes with the normal operation of the furnace or heating system.

Further and more limited obj ects'of the invention will appear as the description proceeds and by reference to the accompanying tributing conduits and the means for creating a forced draft therein and Fig. 2 is a view partly in front elevation and partly in section showing the heating unit connected with a chimney.

The heating unit or furnace 1 may be of any suitable and convenient construction and is provided with a surroundingcasing 2, the latter being provided with a distributing bonboth conduits.

netor dome 3 and into which leads the cold alr intake pipes 4 and 5. The furnace is conncctedwith the chinmey 6 in the usual manner by a pipe 7. Connected with the bonnet 3 is a heat distributing pipe 8 which leads upwardly therefrom and is divided into a pair of branch conduits 9 and 10 leading in difi'erent directions, Disposed at the intersection of the branches 9 and 10 and exterior thereof is a motor 11 which is mounted in a suitable frame 12 which is secured to the conduits adjacent the intersection. 13 projects into the main conduit and secured to the inner end thereof is a fan 14. As seen in Fig. 1 the fan is so disposed with respect to the pair of branch conduits 9 and 10 as to discharge into and to create a forced draft through both of said branches. C0mmunieating with the branch conduit 10 and intersecting the same at an angle thereto is an auxiliary conduit 15 and communicating with the end of the branch conduit 10 are a plurality of auxiliary conduits 16 and 17 which also intersect the branch conduit 10 at an angle thereto as shown in Fig. 1. The conduits 9 and 10 are shown as extending in op posits-directions but they may lead to any part of the building to be heated. The plurality of auxiliary conduits 15, 16 and 17 connect with the branch conduit 9 and may connect at their delivery endwith a hot air register. Auxiliary conduits 18, 19 and 20 connect with the branch conduit 10 and are identical with the conduits 15, 16 and 17. lit

v will be noted that each of the auxiliary conduits intersect the branch conduits at an angle thereto. Positioned adjacent each intersection and between the branch and the The motor shaft auxiliary conduit is an electric motor 21' having a shaft 22 projecting into the intersection and carried by each, of the shafts 22 is a fan 23 and it will be seen that the fan 23 is so disposed as to create a forced draft in The motors 21 and the mountings for the same are identical with the motor 11 previously described.

The cold air inlet-pipes 4 and 5 may be connected either with the outside air or with the room to be heated near the floor thereof. Cold air will be taken in through the cold air inlet pipes A and 5 anddrawn in over the furnace 1 and into the bonnet 3. The motors may be-of the adjustable speed type, if desired, and ,create sufficient suction .to draw the warm air through the pipe 8 and deliver the same into the branch conduits 9 and 10. For large office buildings and factories several additional motors and auxiliary conduits may be necessary to effect a proper distribution of the heat but in small-buildings or homes one motor will often be sufficient to thoroughly distribute the heat.

In this manner clean healthy warm air is delivered to every part of the structure to beheated. The heat distributors are placed at strategic points along the pipe to efficiently force the warm air into every part of the room to .be heated. Areas about outside ex posed walls are heated to the same comfortable temperature as in the center of the room. Comfortable temperature is obtained almost immediately after the furnace is fired and should the room become overheated connections may be rovided for discontinuing the motors. Pre erably each of the auxiliary conduits connect at their delivery end with a heat register, although the same is not necessary. If the cold air intake pipes 4 and 5 are connected with the room to be heated, the cold air which naturally falls to the floor is taken in through the intake pipes and returned to the furnace and warmed and rede livered to the room as warm air. The air in the room is being continuously circulated and returned to the heating unit as soon as it becomes sufficiently cold to fall to the bottom of the room. In this way a clean healthy heat is being continuously delivered to the room and there will be no oul all remaining in the room.

In temperate or tropical climates my system may be used as a ventilating or cooling system and in such cases the cold air pipes may be connected to the outside air and the heating unit may be replaced by a cooling unit if desired and suitable means may he provided for filtering and cleaning the air before it is drawn into the building.

The motors may be either constant or variable speed motors and the size of the same depends upon the size and type of heating unit, the size and type of the building to be heated and the normal climatic conditions.

Various changes may be made in my construction'without departing from the spirit of my invention and I. wish the same to be limited only in accordance with the scope of the appended claims.

Having thus described my invention, what I claim is a 1. A heating and ventilating system comprising a heating unit having an inlet for fresh air, a main conduit leading from said heating unit and having a pair of branches leading in different directions, a motor disposed between said pair of branches and having a shaft projecting into said main conduit, a fan carried by said shaft and so disposed as to produce a forced draft through each of said branches, a plurality of auxiliary conduits communicating with said pair of branches respectively and leading in different directions, a motor disposed between each ofsaid auxiliary conduits and thebranch with which it communicates and having a shaft projecting into and disposed adjacent the intersection, a fan carried by said shaft and adapted to discharge into both the branch and auxiliary conduit, each of said branches coiimunicating with a register at its delivery en 2.
